Buy a business or start one? What 15,500+ real listings say about the startup years

The short answer

Every page that ranks for this question lists the same pros and cons: cash flow on day one, trained staff, easier financing on one side, control and lower cost on the other. None of them measures what a young business earns compared with an old one. This page does, using Main Street Index, BigIdeasDB's census of 84,900+ businesses-for-sale listings from 29 marketplaces. We cut it to the 49,900+ listings priced in US dollars on an owner earnings (SDE) basis, then to the 15,500+ that state a founding year, an asking price and positive SDE, after removing 950+ templated look-alikes.

SDE is the profit a single owner-operator takes out: net profit plus the owner's pay and personal add-backs. All prices are asking prices from live listings, not sale prices, and all earnings are stated by sellers. A listing that is three years old is a business that survived three years and chose to sell, which is the closest public view of where a startup stands at that age.

Four sibling pages cover the ground around this one, and this page does not repeat them. The disadvantages of buying an existing business measures goodwill and owner dependence. Our business success rate study covers survival odds and how the asking multiple rises with age. The best business to start or buy by budget sorts both paths by cash on hand, and what business should I start filters industries by capital, hours and licences. This page answers the question underneath all four: how long are the startup years in your industry, and what do they cost?

Buying vs starting a business, side by side

Buying a business 10+ years old costs about 1.9 times as much as buying one 3 years old or younger, and it earns about 1.6 times as much (Main Street Index, 15,500+ screened US listings, October 2026). Starting costs less than either, and earns nothing until it does.

Two of these shares differ from figures on our other pages because the population is different. Seller financing appears in 20.1% of all US-dollar listings, but in 27% to 28% here, because listings that state a founding year, a price and earnings are the more complete listings. Owner-operated is 53.1% of all US-dollar listings stating a role; here it rises with age, from 46.0% to 58.2%. “Hands-off” on this page means absentee or semi-absentee, and excludes manager-run listings.

The middle group matters too. Businesses 4 to 9 years old (4,200+ listings) state a median $142K of SDE at a $300K ask: 81% of the established earnings for 67% of the established price. For deal mechanics on any of the three columns, see how to buy a business and how much down payment you need.

What do businesses earn at each age?

Median stated SDE climbs from $98.6K for businesses in their first two years to $196.1K for those 30+ years old, but most of the climb happens by year five: a business 4 to 5 years old states 86% of what a 10 to 19 year old one does (Main Street Index, October 2026).

Three patterns stand out. First, half of businesses listed within their first two years already state $100K or more of SDE (49.7%). Those are survivors with something to sell, not typical startups, but they show the ceiling a fast start can reach. Second, young businesses run higher margins on smaller revenue: 27.0% in the first two years against 22.4% at 30+. Revenue keeps growing for decades; margin does not. Third, after year five the earnings line flattens while the price keeps rising. Asking prices climb 84% from the 4 to 5 year band to the 30+ band, while SDE climbs 42%.

That third pattern is the one our success rate study measures from the price side: older businesses ask a higher multiple of earnings. Seen from the earnings side, the same fact means the startup years, in the sense of the years when earnings are still catching up, mostly end around year five. After that you pay for longevity, not for income. For how price and earnings combine into a valuation, read how to value a small business and how much a business is worth.

How long are the startup years in each industry?

Across 30 US industries with 30+ listings on both sides, businesses 5 years old or younger state anywhere from 38.9% (pool service) to 123.1% (other home improvement) of an established one's median SDE (Main Street Index, October 2026). That share is the best public measure of how long a start in that industry takes to catch up.

Read the “young as % of established” column first. Above about 90%, a young business already earns what an old one does, so the startup years are short and what you pay extra for age buys history, not income. Below about 60%, the startup years are long, usually because the business grows account by account, crew by crew or contract by contract. The payback column divides the extra asking price of an established business by the extra SDE it states.

The industries split into three groups. Short startup years: fast food, bakeries, pizzerias, specialty food retail, food wholesale and seafood restaurants, where young listings state 93% or more of established earnings. A food business that survives its first years reaches its earnings ceiling quickly, because the ceiling is set by the room and the street, not by years of accumulated customers. Long startup years: pool service, general contracting, food trucks and vending, commercial cleaning, pet services and cafes, where young listings state 39% to 67%. These build a book of recurring accounts or contracts over time. The middle: restaurants, landscaping, HVAC, bars, gyms and auto repair, where young listings state 81% to 87%.

A few rows run above 100%, meaning young listings state more SDE than old ones: beauty services, nail salons, seafood restaurants and other home improvement. Treat those as a sign that the young listings in those industries are a different kind of business (newer formats, franchise units or larger operators), not as proof that age lowers earnings. The industry guides go deeper on each: buying a pool route, whether a cleaning business is profitable, buying a landscaping business, buying an HVAC business, buying a coffee shop and buying an auto repair shop.

What does the age premium actually buy?

Across all 15,500+ screened US listings, an established business asks $210K more than a young one and states $66K more SDE, so the extra price pays back in about 3.2 years of extra earnings (Main Street Index, October 2026). By industry the payback runs from half a year to eight years.

Short paybacks mean the market barely charges for age even though older businesses earn far more. Spas and massage (0.5 years), building and property maintenance (0.6), food trucks and vending (0.7), commercial cleaning (1.3) and hair salons (1.3) all sit there. In commercial cleaning, an established business asks $125K more than a young one and states almost $100K more SDE a year. If you are buying in one of these industries, buying older is cheap.

Long paybacks mean you are paying for history. Landscaping (8.1 years), HVAC (7.2), clothing retail (5.8), auto repair (5.7), bars (5.6) and pizzerias (5.3) charge far more for age than the extra earnings justify. A young landscaping business 5 years old or younger asks a median $227.9K for $171.4K of SDE (54 listings); an established one asks $532.5K for $209.1K (208). The extra $304.6K buys about $37.7K a year. Part of that premium is equipment, crews and commercial contracts that do not show in SDE, so it is not automatically overpriced, but it is the gap to negotiate on.

“A business that sustainably throws off $100K/yr with only a few hours per week from the owner is likely going to be worth $300K - $500K or more.”r/Entrepreneur, on buying vs starting

For a single listing, the business price checker places its price against similar listings in the same industry and price range. Our guide to negotiating a business purchase covers how to use a gap like this at the table.

How much does it cost to start vs buy a business?

Starting is far cheaper in cash for service businesses and not cheaper at all for restaurants. A cleaning trade association puts average startup costs near $3.5K against a $200K median ask for a young US commercial cleaning business; a restaurant survey puts the median cost to open at $375.5K against a $299K ask for a young US restaurant.

Our data covers businesses for sale, not startups, so every startup cost below is external and labelled with its source. These are industry estimates, not audited costs, and each source has an interest in its topic. Use them as orders of magnitude.

Sources: the RestaurantOwner.com cost-to-open survey of 350+ independent restaurant owners; Crimson Cup's coffee shop cost ranges, drawn from owners in its own program as of August 2026; Mobile Food Alliance's food truck prices; and the International Janitorial Cleaning Services Association. The SBA's startup cost worksheet lists the categories to price for any other industry, and our startup cost calculator totals them. For general ranges across industries, see how much it costs to start a business.

The table gives three distinct answers. In commercial cleaning, starting costs about 2% of buying a young business, so starting wins on cash if you can wait for contracts. In pool service, a young route asks about one year of its own SDE ($69K for $64K), so a small route costs little more than the marketing to build one and arrives with customers. In restaurants, the young listing costs less than the build, which is the case worth a closer look.

Restaurants: buying a young one costs less than opening one

The median US restaurant for sale that is 5 years old or younger asks $299K for $144K of stated SDE (364 listings, Main Street Index, October 2026), while the median independent restaurant in the RestaurantOwner.com survey cost $375.5K to open. Buying the young restaurant is cheaper than building it and arrives with a fitted kitchen and a trading history.

The same survey reports a median annual profit of $71.3K for open restaurants, with the bottom quarter at zero. That is profit after any owner pay the survey respondents counted, so it is not directly comparable to SDE, but it shows the spread: a new restaurant can work, and a quarter of surviving ones earn nothing. A young listing at least states what it earns. Our restaurant buying guide covers how to test that claim against rent and sales, and why simpler food formats score better for buyers.

The caveat is selection. A restaurant sold at three years old was built by someone who chose to leave. In our study of why owners sell, young businesses are far more often sold for other ventures or relocation than for retirement, and our success rate study shows the same shift by age. Ask for monthly sales since opening, not the best twelve months.

How long does it take a new business to pay you?

Restaurants in the RestaurantOwner.com survey report a median of 5 months to profitability, with the middle half between 2 and 12 months. Profitability is not a salary: listing data shows businesses 2 to 3 years old state a median $114.6K of SDE against $160K at 10 to 19 years (Main Street Index, October 2026).

The gap between “profitable” and “pays me what my job did” is where most start-or-buy decisions are actually made. A founder leaving an $80K job typically draws little or nothing in the first year, then a partial salary until the business reaches the earnings of an established one. In the long-ramp industries above, that is several years.

“Starting a business is signing up for a job too, you just usually don’t get paid for 1+ years. Buying bypasses that period.”r/Entrepreneur, on buying vs starting

“We have been open almost a full year... & have not seen even a $3,000 month.”r/Laundromats, an owner of a new build

Count what the salary gap costs. Self-employment also means paying both halves of Social Security and Medicare through self-employment tax and buying your own health cover, which a commenter in a September 2026 r/smallbusiness thread worked through:

“Congrats- you’ve just taken almost a 20% reduction in net pay for being self employed.”r/smallbusiness, on leaving a corporate job

That cost applies whether you start or buy. The difference is timing: a buyer starts drawing from the business in month one, out of SDE that already exists; a founder waits for it to exist. If you plan to start while still employed, one-person business ideas and low-cost business ideas list the formats that can run on evenings first.

What is left after the loan?

After debt service on 90% of the asking price, the median established business leaves $93K to $100K before the owner's salary, against $63K to $70K for businesses 3 years old or younger (10.5% over 10 years, Main Street Index, October 2026). Per dollar of down payment, younger businesses return more: 3.0x in the first two years against 1.9x at 30+.

That is the trade in one line. Older businesses leave more dollars; younger ones leave more per dollar you put in, because they ask less. The lender test favours older businesses slightly: after an $80K owner salary, 48.4% of established listings cover their debt 1.25 times, against 38.3% of young ones. The base for these tests is the asking price, not the ask plus closing costs and working capital, so real coverage is a little lower. The SBA 7(a) program sets the loan terms most first-time buyers use.

A startup has no version of this test. Lenders finance history, so a founder usually funds the build from savings, home equity or a small loan with a personal guarantee. That is why the cash comparison in the previous section is not the full comparison: a buyer can turn $45K of equity into a $450K business, and a founder usually cannot borrow against a plan. Our guides to seller financing and down payments cover how buyers stretch that equity further, and the hidden costs of buying a business covers what sits on top of the ask.

“So, it's safe to assume that the opportunity cost is about 20k per year.”r/smallbusiness, on an inheritance

That commenter was pricing $400K left in an index fund at 5% a year. Whichever path you choose, compare it against doing neither.

Who does the work: young vs established

Older businesses are more often run by the owner: 58.2% of established listings stating a role are owner-operated against 46.0% of those 3 years old or younger, and hands-off (absentee or semi-absentee) runs 32.7% against 46.6% (Main Street Index, October 2026).

That cuts against the usual pitch. Buying an established business is often sold as escaping the grind of a startup, but the established business is more likely to be a job the seller did personally for decades. Young listings are more often franchise units and semi-absentee formats: 19.5% are franchise resales, against 8.8% of established ones, and owner hours stated in listings rise from a median 11.5 to 20 a week across the age bands (on fewer than 200 listings per band, so treat it as directional).

“Usually, people don’t sell easy businesses. The only exception is when they are too old and retiring. You are often buying a job.”r/Entrepreneur, on buying vs starting

“Most small businesses are essentially buying yourself a fulltime+ job with stress and headaches to boot.”r/smallbusiness

Buying a job is not a bad outcome if the job pays more than the one you leave and you want it. The easiest small businesses to run study ranks industries by owner hours and staff, and buying from a retiring owner covers the transition when the seller is the business.

How to read a young business for sale

Young listings are not a cheaper version of old ones. 19.5% of US listings 3 years old or younger are franchise resales, and excluding them their median SDE is $117K (1,300+ listings) against $182K for non-franchise businesses 10+ years old (8,700+), per Main Street Index, October 2026.

Three questions sort a good young listing from a bad one. Why is a business that just reached profit being sold? Our success rate study shows young businesses are sold far more often for other ventures and relocation than for retirement, which can be true or can be cover. Do the earnings depend on a franchise system, a manager or a lease you are not getting? And is the trend up or down? A young business in a long-ramp industry should still be growing; a flat one may have hit its ceiling early.

A declining business is a separate case, and the replies to a February 2026 r/buyingabusiness thread on exactly this choice were blunt:

“Consider forecasting the business will continue to drop for another 12 months before it stabilizes, while you pump in 20, 50, $100k into recovering it.”r/buyingabusiness, on a declining pet care business vs starting one

“At that point you gotta ask if could you just build this yourself”r/buyingabusiness, same thread

Do 90% of startups fail?

Not small businesses. The Bureau of Labor Statistics finds about 79% of new US establishments survive one year, about half survive five and about a third reach ten, and it reports that 34.7% of establishments born in 2013 were still operating in 2023.

The 90% figure, repeated in the AI Overview for this query, comes from venture-backed startups, a different population with a different goal. Our business success rate study traces where it comes from. For the start-or-buy question, the useful survival fact is this: 61.7% of the screened listings in this study have already run 10 years or more, so a buyer of a typical listing is buying something that beat the odds a founder faces. What no public dataset measures is how often a business fails after it is bought, so figures you may see for acquisition success rates are not traceable to a study.

What buyers and founders say

Forum threads that rank for this question split along the same line as the industry data: experienced operators favour buying, and people still learning the trade are told to start (Reddit threads from 2020 to 2026, anonymized).

“If you don't know why it's better to buy, it's better for you to start one.”r/Entrepreneur, top reply on buying vs starting

“The slower ramp up of a startup would be a bit more forgiving as you get your feet under you and learn the dynamics of the business.”r/buyingabusiness, to a first-time buyer

“Are you ready (and can afford) to work for little/no pay for 12+ months?”r/buyingabusiness, a buyer under LOI on a declining business

“If you can't figure out how to get a business off the ground with $10k then $100k will only change one thing - close the business in 18 months or whatever, instead of 3 months.”r/smallbusiness, September 2026

“As a business lawyer, I can tell you that MANY small businesses are a terrible buy.”r/Entrepreneur, a business lawyer

“I bought one and made a bunch of changes thinking it would improve business but it didn’t.”r/Entrepreneur, a founder who also bought

None of these is evidence on its own, and they come from self-selected commenters. They are useful because they name the two failure modes the data cannot see: a founder who runs out of runway, and a buyer who breaks a working business by changing it. For more owner voices by industry, the pain points database holds 1M+ data points.

When starting a business wins

Starting wins when the build is cheap, the startup years are short or you can wait them out, and you already have the skill. In the data, that points to food concepts you can open small and service businesses where a young listing asks 2 to 3 times what the equipment costs (Main Street Index, October 2026).

• You have the trade and the customers. A licensed technician or a cleaner with three contracts already has what a buyer pays goodwill for.
• The startup cost is tiny next to the ask. Commercial cleaning ($3.5K average start against $200K young asks) and pool service built account by account are the clearest cases, if you can live on little for a year or two.
• You can keep a salary while it ramps. Running it on evenings and weekends removes the biggest risk of starting.
• You want a format nobody sells. If no listing matches the concept, there is nothing to buy.

Our guide to starting a business with no money and the free business idea evaluator help test a start before you spend on it. Local business ideas and home service business ideas list the formats with the lowest build costs.

When buying a business wins

Buying wins when you need income in year one, the startup years in your industry are long, and the age premium pays back quickly. Commercial cleaning, building maintenance, spas and hair salons combine young listings earning 48% to 75% of established ones with paybacks under 1.5 years (Main Street Index, October 2026).

• You are replacing a salary. A buyer draws from existing SDE in month one; a founder waits.
• The industry grows by accounts or contracts. Pool service, cleaning and general contracting take years to build a book a buyer gets on day one.
• The build is expensive. Restaurants, cafes and anything with a fit-out cost about as much to open as a young one costs to buy.
• A licence or certification is the bottleneck. Buying a business with a licensed manager in place can be faster than earning the licence.

Buy or start: the decision table

Each row comes from the medians and shares above (Main Street Index, 15,500+ screened US listings, October 2026).

If you are still choosing an industry, what business should I start filters 55 business types by capital, hours and licences, and the best business to start or buy by budget sorts both paths by cash on hand.

Six checks before you choose

Run these in order. The first one decides how much the other five matter.

1. Find your industry's startup gap. Look up how much a business 5 years old or younger earns compared with one 10+ years old in your industry. Under about 60%, the startup years are long; above about 90%, they are short.
2. Price the start honestly. Add build-out, equipment, licences and at least six months of operating cash, then add the salary you will not draw while it ramps. Use real quotes, not franchise brochures.
3. Price the purchase honestly. Take the asking price, add working capital and closing costs, and run debt service at your real rate and term. Subtract a salary you can live on and check coverage stays above 1.25x.
4. Compare the age premium with the earnings gap. Divide the extra price of an established business by the extra SDE it states. Under 3 years of extra earnings is a fair premium; 7+ years means you are paying for history, not income.
5. Check who earns the money. Ask the seller to state hours, role and whether a manager or franchise system stays. A hands-off young listing and an owner-run old one are different jobs.
6. Decide what you can survive. If you cannot go 12 months without a salary, starting is the riskier path. If you cannot carry a personal guarantee, buying is.

To run the first check on live data, filter by industry and founding year in the listings explorer or compare industries on the industries page. The guide to buying a business with Main Street Index walks through the filters, and the due diligence guide covers the checks after you pick a listing. The AI buyer thesis guide explains the per-listing summary. The SBA's own guide to buying an existing business or franchise lists the documents to request.

What this data cannot tell you

• Survivors only. Every young listing survived long enough to be sold. Startups that closed are invisible, so young-listing earnings overstate what a typical start reaches. The gap between a typical start and an established business is wider than these medians show.
• Different businesses, not the same business over time. A 3-year-old listing and a 20-year-old listing are different firms. The age bands compare populations, not one business growing.
• Asking, not closing. Prices are asking prices; closed deals usually come in lower. SDE is stated by sellers, not verified.
• Founding years are stated by sellers. About half of US-dollar listings give one (26,600+ of 49,900+), and those that do may differ from those that do not.
• Start costs are third-party estimates. Each comes from a survey, a supplier or a trade association with an interest in its topic. None is audited.
• Restaurant profit is not SDE. The survey's profit figure and listing SDE count owner pay differently, so we compare build cost with asking price, not profit with SDE.
• Owner role and hours are thin. 670+ young and 3,300+ established listings state a role; fewer than 200 per age band state hours.

Methodology and data sources

All queries ran read-only against Main Street Index tables on October 5, 2026. The population is de-duplicated listings priced in US dollars on an SDE basis (49,900+), cut to those stating a founding year between 1850 and 2026, an asking price and positive SDE (16,500+). Age is 2026 minus the founding year. We removed 950+ templated look-alikes: the same industry, SDE and revenue repeated 3+ times across 2+ states, or the same description opening repeated 3+ times across 2+ states, leaving 15,500+ listings (99.8% in the US). Industry comparisons use young (5 years or less) and established (10+ years) medians where both sides have 30+ listings: 33 industries, of which we exclude courier and delivery (route listings repeat semi-absentee templates our screens do not fully catch), care homes and home care (new-unit franchise offers price young listings above established agencies) and unclassified listings. The debt test assumes 10% down, 90% of the asking price borrowed at an illustrative 10.5% fixed over 10 years, an $80K owner salary and 1.25x coverage, per listing. Medians are withheld below n=30. Industry labels come from Main Street Index's classifier. Reproduce any cut with the Main Street MCP tools and the Main Street Index docs, or request one through custom data requests.
